PEDER M. JORGENSEN, 0F MILLTOWN, WISQON'SIN'F QUAGK-GRASS DESTROYER.

Application filed May 18, 1922. Serial No. 561,961.

To all whom it may concern:

Be it known that I, Penna M. JoRonNsnN,

a citizen of the United States, residing at Milltown, in the county of Polk and State of Wisconsin, have invented certain new and useful Improvements in Quack-Grass Destroyers, of which the following is a specification.

This invention relates to quack grass destroyers and the object is to provide a comparatively simple but efficient machine of said kind.

In the accompanying drawing:

Fig. 1 is a top or plan view of my improved quack grass destroyer.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is a rear end elevation of the machine with the plow omitted.

Fig. 4; is a side view of one of the shaker bars. I

Referring to the drawing by reference numerals, the main frame is composed of angular side bars 5, a front cross bar 6 and two cross bars 7 and 8 secured in brackets 9 and 10 respectively. The rear bar 8 has its ends offset downwardly and formed into skeins 11 on which rotate the rear ground wheels 12 having lugs 13. The front bar 7 ma also be offset to form skeins 14 for the front wheels 15 but, as shown, the skeins let may be short shafts fixed in the brackets 9.

Secured to each rear wheel 12 is a gear 16 meshing with a pinion 17 fiXed on a multiple crank shaft 18 journaled across the rear portion of the main frame 5. Engaged by the several cranks of shaft 18 is a series of boxes 18 (see Fig. 4) fixed to a series of parallel shaker bars 19 each of which has its upper side provided with a series of upright rearwardly inclined fi-ngers2O and 1ts front end pivotally attached to a stirrup 21 suspended from the bar 7.

Suitably connected to the front frame bar 6 is a draft bar 22 having draft appliances 23 for draft animals, or a tractor may be hitched to the draft bar.

Hitched to the draft bar 22 or any other suitable extension from the front "part of the frame is the beam 24 of a plow 25, which 'is thus drawn along with the frame close by shaft 18 at a considerable 5 speed cause the furrow to be shattered and its dirt shaken down between the bars 19iwhile the fingers 20 move the quack grass and its roots rearward, depositing it on the ground, where gets dry and is then'raked into heaps and burned.

What I claim is:

frame mounted on ground wheels and adapted to be drawn forward, a multiple crank I I 1. In a quack grass destroyer, a skeleton shaft journaled across the frame, a series bars and having the front end of its beam 1 operatively connected with the front end of the frame. i I

2. The structure specified. in claim 1. the f i said operative connection between the plow' and the, frame comprising a draft bar secured to the frame and projecting laterally beyond the front end of the same and having draft appliances. for hitching some motive power to it.

, 3. The structure specified in claim 1,

- said plow having its mold board projected considerably in over the shaker bars.

In testimony whereof I afiix my signature. 1 I
